This is really what my program is for: finding the ‘islands’ that are marked with the same value. By the way, this map can be put through my program if you format it as a 2d array first.

Edit: explanation of program purpose

This program can be thought of as finding the ‘islands’ in a matrix. For example, this ‘map’ has the blue and red islands with water in between. This program would tell you which areas are whose, and where the water is:

~BB~~~~RRR
~~BB~~~~~~
~~~~~~R~~~
~~B~~RR~~~
~~~~~~~~~~

Here is an image that describes what the program is finding in the first example. The output of the program is comprised of lines starting with the value, then a colon, and then the coordinates of the set of connected nodes with that value.
